The magnetic field flux is expressed in


ANSWER

Weber


SOLUTION
Magnetic Flux is defined as the number of magnetic field lines passing through a given closed surface. It gives the measurement of the total magnetic field that passes through a given surface area. S.I. unit of magnetic flux is Weber $$(Wb)$$.

Q1 Single Correct Medium
The frequency ($$n$$) of a tuning fork depends upon the length ($$L$$) of its prongs, the density ($$d$$) and Young's modulus ($$Y$$) of its material. It is given as $$n\propto L^{a}d^{b}Y^{c}$$. The values of $$a, b$$ and $$c$$ are :
  • A. 1, 1/2, -1/2
  • B. -1, - 1/2, 1/2
  • C. 1/2, -1, -1/2
  • D. 1/2, -1/2, 1

Q3 Single Correct Hard
In a hypothetical reaction, $$A(aq) \rightleftharpoons 2B(q) + C(aq) (1^{st}$$ order decomposition)
$$'A'$$ is optically active (dextro-rototory) while $$'B'$$ and $$'C'$$ are optically inactive but $$'B'$$ takes part in a titration reaction (fast reaction) with $$H_{2}O_{2}$$. Hence, the progress of reaction can be monitored by measuring rotation of plane polarised light or by measuring volume of $$H_{2}O_{2}$$ consumed in titration.
In an experiment the optical rotation was found to be $$\theta = 40^{\circ}$$ at $$t = 20\ min$$ and $$\theta = 10^{\circ}$$ at $$t = 50\ min$$. from start of the reaction. If the progress would have been monitored by titration method, volume of $$H_{2}O_{2}$$ consumed at $$t = 15\ min$$. (from start) is $$40\ ml$$ then volume of $$H_{2}O_{2}$$ consumed at $$t = 60$$ min will be:
  • A. $$60\ ml$$
  • B. $$75\ ml$$
  • C. $$52.5\ ml$$
  • D. $$90\ ml$$
